To all whom it' may concern,.-

Be it known that I, JAMES T. HAMBAY, a citizen of the United States, anda resident of the city of New York, county of New York, State of NewYork, have invented certain new and useful Improvements in SignalingApparatus, of which the following is a specification.

My invention relates to an improvement in signaling apparatus, and isespecially adapted to the operation of semaphore-signals.

In the following I have described, with reference to the accompanyingdrawings, several means for carrying out my invention, the particularfeatures thereof being more fully set forth hereinafter in the claims.,m

Figure 1 is an elevation of a signal-post, showing a semaphore in normalor danger position. Fig. 2 is an elevation, partly in section and on anenlarged scale, of the case, showing the bearings, the semaphore beingremoved. Fig. 3 is a diagrammatic view of the phases of motion of theoperating mechanism `of Fig. 2. Fig. 4 is an elevation, partly insection and on an enlarged scale, showing a modification. Fig. 5 1s aplan view of the parts shown in Fig. 4 looking in the direction of thearrows. Fig. 6 is an elevation of apparatus, showing a secondmodiiication, parts being broken away.

Similar numerals of reference indicate similar parts throughout theseveral views.

1 indicates a signal-post suitably supported on a foundation 2 andhaving a case 3 adapted to form bearings for certain of the operatingmechanism of the semaphore 4. Operating-rod 5 is adapted to be actuatedby any suitable mechanism. At its upper end, as shown in Figs. 2 and 3,rod 5 is pivotally connected at points 6 and 7 to links 8 and 9respectively, which in turn are pivotally conneoted to the side wall ofthecase 3, as shown at points 10 and 11, respectively. A crankarm 12 isfast on shaft 13, having bearings in the side wall of the case.Semaphore-signal 4 is fast on the outer end of shaft 13 and partakes ofthe motion thereof. The other end of crank-arm 12 is slotted, as at 14,to receive the roller 15 on rod 5.

As shown in Fig. 4, rod 5 is bfurcated, having arms 16," between whichroller 15 1s mounted. Roller 15 is adapted to travel in a platepreferably made in two parts 17 and 18, one on each side of the rollerand each provided with a slot 19 to receive the roller. The plate issupported in the case 3 1n any suitable marmer, as on bolts 20. It isobvious that the shape of the slot may be varied to cause the roller totravel any* predetermined path. .z i

As shown in Fig. 6, my invention is illustrated as applied to thesignal-tower end of rod 5, the signal-post end being constructed in thecustomary way, (not shown,) rod 5 being pivoted directly to crank-arm12. In Fig. 6, 21 indicates a frame, to which a bellcrank having arms 22and 23 is pivoted, as at 24. Crank-arm 22 is provided with aspringlatchrod 25 for holding it in position in the usualway. Links 26 and 27 arepivotally connected at one end, as at 28 and 29, respectively, to frame23 and at the other end, as at 30 and 31, respectively, to rod 5. Theouter end of crank-arm 23 is slotted, as at 32, the slot being adaptedto receive a roller 33, supported on rod 5.

As shown in Figs. 2 and 4, the result of the arrangement is to lengthenthe stroke of crankarm 12, and, as shown in Fig. 6, the result is toshorten the stroke of crank-arm 23, the said results being equivalent toeach other.

The parts are preferably so proportioned and connected that thecrank-arm on shaft 13 is caused to move through substantially equaldistances lduring each equal interval of time, thus in turn causing thesemaphore during each equal interval of time to move throughsubstantially equal vertical distances. The advantage of thisarrangement is that it results in a substantially constant leverage inmoving the semaphore from the normal t0 clear position, and vice versa.Should it be desired to cause'a variable leverage by any of the meansdisclosed, the proporltions could obviously be changed accordin y.

gIhe ends of slot 14 in crank-arm 12 may be provided with knife edges 34and 35, as shown in Fig. 2, so as to assist in cutting ice or snow whichmay collect in the slot.

It is obvious that the details of construction can be varied and thatdierent means may be employed to accomplish the object of the inventionWithout departing from the spirit thereof.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. In a signaling apparatus a crank-arm and means for varying thedistances between its centers during the operation thereof whereby theleverage on said arm is substantially constant.

2. In a signaling apparatus a crank-arm and means for actuating. thesame, the parts being so arranged that the leverage on the crank-arm issubstantially constant.

, 3. In a signaling apparatus a rod, a crankarm and means actuated bysaid rod adapted to travel on said arm so as to vary the distancesbetween the centers of said arm during the operation thereof whereby theleverage on said arm is substantially constant.

4. In a signaling apparatus a rod, means for guiding said rod, a shaft,an arm mounted on said shaft and means actuated by said rod adapted totravel on said arm so as to vary the distances between the centers ofsaid arm during the operation thereof whereby the leverage on said armis substantially constant.

5. In a signaling apparatus a rod, a cranl arm and means for guidingsaid rod so as to exert a substantially constant leverage on said arm.

6. In a signaling apparatus a rod, links adapted to guide said rod, ashaft, a slotted arm mounted on said shaft and a roller carred by saidrod and adapted to travel in said s ot.

7. In a signaling apparatus a rod, links adapted to guide said rod andswinging on a predetermined radius, a shaft, a slotted arm mounted onsaid shaft and adapted to swing on a radius. different from that of theguiding-links and a roller carried by said rod adapted to travel in theslot.

8. In a signaling apparatus a shaft, a slotted crank-arm mounted on saidshaft, said slot being provided with` knife-edges at its end.

9. In a signaling apparatus a rod, means for guiding said rod, a shaft,a slotted arm mounted on said shaft, knife-edges at the ends of saidslot and a roller carried by said rod and adapted to travel in saidslot.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
